Title: Pll anomaly detection method
Inventor: HIBI YASUMORI
IPC: H03L7/095
Filed: 1978-04-03
Abstract: PURPOSE:To prevent noise to the analogue signal system from mixing in, by mobitoring the digital signal output of a phase detector circuit to perform the ligical processing for out-of-phase. CONSTITUTION:Flip-flops 3 and 7 constitute a phase comparator. Then, outputs of these flip-flops have the phase opposite to each other under a synchronous state. Here, in case of any out-of-synchronism, exclusive OR 8 outputs a pulse corresponding to out-of-synchronism width, however, anomaly is not detected if this width is within tolerance r. When out-of-synchronism is longer than time r, OR 10 between a signal, which is delayed by time r in delay circuit 9, and a signal, which does not pass through the delay circuit, is operated, and the output as OR is obtained. As a result, anomaly can be detected.

IPC: H02K15/02
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To reduce copper losses in windings in slots while the machining and assembly man-hours of stator steel sheets are not particularly increased. SOLUTION: A stator 1 for a DC motor consists of belt steel sheets 2 piled into a plurality of layers so as to have a cylindrical form which has a plurality of slots 3 on its inner circumference. Each slot 3 is formed narrow at the entrance 3a and gradually widened toward its bottom in which a wedge-shaped cut 6 extended in the radial direction of the stator 1 is formed. Each cut 6 has an aperture 6a with a width of not larger than half the thickness of the steel sheet 2. A distance between the tip of the cut 6 and the outer part of the stator 1 is set so as to be 1-2 times the thickness of the steel sheet 2.

When the spot light source 131 reaches the coordinate position Sb, the 1st carriage 411 is stopped and the spot light source 131 is moved at the same time toward a coordinate position Sc at nearly the same speed with the moving speed of the 1st carriage 11. Consequently, the display start position of the erasure range is confirmed accurately on the original.

Title: Video signal detection circuit
Inventor: NISHI HARUHIKO
IPC: H04N5/52
Filed: 1990-02-22
Abstract: PURPOSE:To dispense with a keyed pulse generator and to easily decide a peak AGC start point by comparing a synchronizing signal part and a video signal part separately with two voltage comparators, and adding output with an adder. CONSTITUTION:A voltage source 6A supplies a voltage VA to the voltage comparator 7A, and a voltage source 6B supplies a voltage VB to the voltage comparator 7B. In an ordinary operation, the excess of the tip of a synchronizing signal exceeds the voltage VA is detected with the voltage comparator 7B, while, when a video signal having a remarkably excessive video signal part exceeds the voltage VB, the voltage comparator 7A is operated and issues the output. Generally, a detection circuit is operated so as to keep the size of the synchronizing signal constant, and when an excessive white signal is inputted, the detection circuit is operated so as to keep the size of the video signal part constant. The value of VA decides the peak AGC start point, and it is clear that it is easy to generate a constant voltage value than to manage the length of a pulse at a constant level.
